R-Patz and Kristen get cosy in Canada

Twilight's onscreen lovers Robert Pattinson and Kristen Stewart have been snapped sharing a romantic moment together off-screen.

Pattinson, 24, is said to have flown to Canada to visit Stewart, 20, on the set of her new flick On The Road.

According to E Online, they shared a romantic dinner at Le Club Chasse et Pêche with security and a few friends in tow.

"They were smiling and looked really happy, laughing through dinner," a diner at the upmarket restaurant said. "It's just so clear they are a couple."

Twi-hards have long suspected that the duo is as close off the screen as they are playing lovebirds on the hit show.
